2012 BMW 118i Service and Repair Manual

This factory service and repair manual for the 2012 BMW 118i covers a compact rear-drive hatchback with a small forced-induction engine: a 1.6-liter inline-four of 98 cubic inches, twin-cam and turbocharged, on gasoline. The body is a four-door hatchback and the trims are Base, Sport Line and Urban Line, which differ in equipment rather than in mechanicals. That keeps the engine, fuel and driveline specifications single-valued and pushes the variation into the interior trim, lighting and comfort wiring.

Known issues on the 2012 118i. A small turbocharged engine in a compact body concentrates the work into a tight engine bay, and the manual is written for that: charge-air and turbocharger procedures, boost control testing, high-pressure fuel and injection specifications, timing drive service and cooling circuit bleeding, with torque values and tightening sequences throughout. Around the engine sit transmission and final drive data, brake and suspension procedures, and wiring diagrams for the lighting, locking, climate and instrument circuits, with diagnostics arranged so a reported symptom leads to a specific test.
